From d8346b7d9bab37e6cc712ff1622c65ff98bdfef8 Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Thu, 20 Dec 2012 15:32:08 +0100 Subject: KVM: s390: Support for I/O interrupts. Add support for handling I/O interrupts (standard, subchannel-related ones and rudimentary adapter interrupts). The subchannel-identifying parameters are encoded into the interrupt type. I/O interrupts are floating, so they can't be injected on a specific vcpu.
